Description

201041999 VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to metal-missing salts and their use as emissive materials in illuminating devices. In particular it relates to their use as white light emitters in organic light-emitting devices (OLEDs). [Prior Art] q The white light emitting OLED can be obtained by different techniques. For example, they can be obtained by using a multilayer construction in which each layer has a different emission spectrum and in which the emission spectra of the plurality of layers are complementary and cover the entire visible spectrum, thereby obtaining white light emission. Another method uses a single molecule with a broad emission spectrum. Yet another method uses multiple emitters that emit at different wavelengths in a single layer. Those methods to date involve neutral molecules because they are suitable for small molecule OLEDs prepared by vacuum. The most frequently used method for producing white light emissions involves Q and the fabrication of devices comprising two or three emissive layers. This makes the manufacture of white light emitting devices (WOLEDs) an expensive method that does not compete with actual lighting technology. WO 2006/024997 discloses a trinuclear white light emitter molecule comprising two blue-emitting enthalpy centers, the enthalpy center being coordinated to a red-emitting erbium complex by an organic linkage, wherein The energy transfer from the high energy emission center to the portion of the low energy emission center results in the emission of almost white light. The energy transfer of this portion between the covalently bonded emission centers can be carefully engineered by the connection between the two emission centers (by adjusting the length of the connection group - 5 - 201041999) Take control. This requires lengthy and cumbersome organic chemical treatment. SUMMARY OF THE INVENTION One object of the present invention is to provide an emitter, particularly a white light emitter, that is easy to prepare and in which the degree of energy transfer is easily controlled. In one aspect, the invention relates to a luminescent material comprising a salt of a wrong salt which consists of a group of one or more anionic luminescent moieties which compensate for one or more The charge of a group of the cationic luminescent moiety, wherein at least one of the moieties of the moiety is a complex of the metal, preferably the two moieties are metal complexes. In various embodiments, the portions have complementary emission spectra such that the luminescent material can function as a white light emitting material. Each of the illuminating portions may be a phosphorescent material. In particular, various embodiments of the first aspect relate to a white light emitting material comprising a salt of the general formula, wherein: • xm = yn, • [M^ + l and [M^] light-emitting portions of the ion, They have complementary emission spectra, one emitting in the blue region of the visible spectrum and the other in the red region of the visible spectrum, and wherein at least one of Μ and Μ2 is a metal complex. In a second aspect the invention relates to a process for the preparation of an emissive material according to the first aspect of the invention and in particular a fault salt. In a third aspect, the invention relates to a luminescent device comprising an emissive layer -6-201041999 apparatus' said emissive layer comprising or consisting of a luminescent material according to the first aspect of the invention. In a fourth aspect, the invention relates to the use of a white light-emitting material according to the first aspect of the invention in an emissive layer of a light-emitting device. An advantage of various embodiments of the present invention is that white light emission can be obtained by a single layer of material. A single emissive layer device is easier and cheaper to manufacture. Another advantage of various embodiments of the present invention is that they provide a versatile method for finely tuned emission by allowing for individual optimization of each emitter of the metal mis-salt. Yet another advantage of various embodiments of the present invention is that only a minimum number of synthetic steps are required to prepare the emissive material, whereas the prior art requires a synthetic combination of connectors. Another advantage of various embodiments of the present invention is that the degree of energy transfer between the energy donor and energy acceptor portions of an emitter in accordance with various embodiments of the present invention can be varied by altering the emitter and The polarity of the medium being contacted (local and/or overall polarity), and/or by the concentration of the polar dopant therein is easily controlled. In the prior art, varying the degree of energy transfer implies changing the length of the link by a new synthesis.

It is apparent that other embodiments of the present invention can be configured in accordance with the knowledge of those skilled in the art without departing from the true spirit or scope of the invention. The invention is limited only by the terms of the appended claims. A number of inventors of the present invention have recognized that in order to obtain a single layer emitter, 'if used as an emissive material, a simple mixture of two differently charged ion complexes with two non-emitting opposite ions Will show a variety of inconveniences. A first disadvantage of such a mixture would be that the salts from the opposite ions may crystallize. For example, if a cationic luminescent complex (ie, an ion pair [Μ/ΠΧ〆]) having a relative anion X, and an anionic luminescent complex m2 having a relative cation x2 (ie, an ion pair Q [Μ2Ί] [Χ2 + ]) When mixed together, the salt [xr][x2 + ] may easily crystallize for a long time 'because those relative ions are usually made up of very small molecules (PF6_, . . . ) or atoms that can be firmly bonded ( Cl-, Na+···). And, for example, if an ion pair [Μ/ΠΧ〆], and an ion pair [Μ2 + ][χ2-;| are mixed together, then the two emitted complexes will end on the same side of the device, Thereby increasing the possibility of annihilation. In addition, the preparation of non-crystalline, relatively ionic complexes (such as ionic liquid derivatives versus ions) can be difficult and expensive because an ion exchange step would be required. This step may involve a saturated solution of the relative ions sought in -11 - 201041999, as well as the expected complex; to overcome those synthetic steps, it has been unexpectedly found that the stator bond and more specifically the ion A supramolecular bond can be used to join the two illuminating portions together. In a first aspect, the invention relates to a hair comprising a fault salt consisting of one or more anionic light-emitting moieties that compensate for a charge of one or more anionic light-emitting portions, Wherein at least one of the portions is a misalignment of a plurality of embodiments, the portions have complementary emission spectra. The optical material can function as a white light emitting material. Each hair may be a phosphorescent portion or a fluorescent portion, which is preferably a portion. A plurality of embodiments of the first aspect of the invention relate to a luminescent material comprising a salt of a fault, wherein · 1 is a luminescent portion of a cation, 2. π is an illuminating portion of an anion, 3. xm = Yn, and wherein at least one of Μ 1 and M 2 is a metal complex. In various embodiments, [M^ + h and Å; ^ have an inter-spectral spectrum such that the luminescent material is a white light-emitting material. In one embodiment, the equal salt is characterized by one of [M, [M2n_]y emitting in the blue region of the visible spectrum (from blue to greenish and greenish blue), eg, its emission spectrum has Residues in the range of 550 nm, preferably 390 nm to 520 nm. Electrically super- or more materials of the group of photo-material groups. In the case of the luminescent part, a phosphorescent formula is a supplementary m. + ]x and dark blue 309 nm maximum -12-201041999 emission wavelength) and the other emits in the red region of the visible spectrum (from yellow-orange to red, for example, its emission spectrum is between 550 nm and 740 nm, Preferred is the maximum emission wavelength in the range of 580 nm to 740 nm). In other words, various embodiments of the present invention relate to a white light emitting material according to any of the above embodiments, wherein one of [M^ + h and Y, guang; has an emission spectrum having a maximum emission wavelength in a range of 550 nm to 740 nm And another of its emission spectrum has a maximum emission wavelength in the range of 390 nm to 550 nm. Preferably, the distance between the portions (eg, in the case of an ion pair, between [M^ + h and [M2n" y) is adjusted and/or the portions are selected (eg, selected [ΜΛ + h and [M2n_]y) such that the metal salt is capable of emitting at (0.200, 0.200) to (0.550, 0.500), preferably from (0.260, 0.280) to (0.460, 0.500), More preferably, the light of the CIE 1931 coordinates (X, y) ranges from (0.270, 0.290) to (0.400, 0.400). In other words, various embodiments of the present invention relate to a white light emitting material according to any of the above embodiments, wherein the fault salt is capable of emitting a CIE 1931 coordinate (X, y) having a range from (0.200, 0.200) to (0.550, 0.500) ) the light. This is advantageous because light with such a CIE 1931 coordinate is acceptable for white light. The adjustment of the distance between the parts (eg [ΜΠχ and [M2nJy]) can be carried out by including the wrong salt in a matrix, preferably dispersed in a matrix, wherein the metal is surrounded The polarity of the matrix of the salt (e.g., the overall and/or local polarity) is adjusted to provide a distance between the illuminating portions such that emission of white light can occur. When a substrate is present, the wrong salt (i.e., the object sought) can be 0.05% -13 - 201041999 or more, preferably ο · 1 ο % or more, particularly preferably 0.15% Or more and especially preferably an amount of 0_2% or more is present. The object can be present in an amount of 20% or less, preferably 15% or less, particularly preferably 1% or less, and particularly preferably 5% or less, wherein the upper limit Any of the above may be combined with any of the above lower limits. Embodiments of the present invention are directed to a luminescent material comprising a fault salt as defined in any of the above embodiments and a substrate, wherein the polarity of the substrate is sufficient to provide a distance between the illuminating portions such that white light is emitted Can happen. The substrate can be a liquid, gel or solid polar, nonionic medium. The substrate is preferably a solid medium. The main component of the matrix is preferably nonionic but the nonionic matrix can be doped with a polar species such as the species of ions. In various embodiments, the non-ionic substrate can be aprotic. Preferably, the substrate comprises a polymer as its primary or sole component. Optionally, the optical properties of the substrate (e.g., ' its absorption characteristics) can be used to adjust (e. g., correct) the emission spectrum of the luminescent salt. The substrate is preferably permeable to visible light. A good way to provide a substrate suitable for providing a sufficient distance between the portions is to select a substrate of a polarity. Preferably, the substrate has a polarity at least equal to the polarity of the poly(vinylpyrrolidone) (PVP), i.e., less than 3.0. Suitable polar matrices further function as a hole transport and/or electron transport organic semiconductor, including, for example, poly(vinylcarbazole) (P V K) and/or polymeric or non-polymeric oxadiazole. The dielectric constant (or relative electrostatic dielectric constant) is a measure of the macroscopic polarity of the matrix -14-201041999. If the dielectric constant of the matrix is less than the dielectric constant of PVP (e.g., less than 3.0), it is preferred to include one or more second components (or "dopants") in the matrix. Those dopants are molecules of polarity. Those polar molecules are preferably capable of loosening or breaking one or more electrostatic (ionic) bonds in the wrong salt that are attached to the plasma portion. These dopants are preferably ionic salts. The salt of the ion will indicate the separation of the emitting moieties. Examples of dopants are salts of organic cations with either organic or inorganic anions. When in liquid form, they are meant to mean ionic liquids or molten salts. The ionic liquid comprises a molten salt which is liquid at room temperature and which may also comprise a so-called "ambient temperature molten salt" having a lower than 15 (TC, preferably less than 80 t and more preferably Is a melting point below 30. (: melting point. The ionic liquid system consists of a cation and an anion (as in a regular salt). The distinguishing feature is the low melting point of the compound. Its melting point can be lower than room temperature or At relatively low elevated temperatures (〇, for example, 1 50 ° C), such that they are compatible with the polymerized membrane (when in their liquid state). Examples of cations for ionic liquids are: Double and disubstituted imipenyl green, 卩it u key, sputum iron, chew π fixed gun, lyrics key, pyrazine iron, pyrazole key, thiazole key, oxazole key, triazole iron, phosphorus Keys, ammoniums, samariums, and isoureaces. Examples of anions used in ionic liquids are: halides, sulfates, sulfonates (eg, trifluoromethanesulfonate ("trifluoro Mesylate salt, CF3S〇3-)), guanamines, quinones (for example Bis(trifluoromethylsulfonyl) quinone imine ((N(CF3S02)2-), bis(perfluoroethylsulfonyl) quinone imine ((C:2F5S〇2)2N·)), A Bases (eg -15-201041999 'Tris(trifluoromethylsulfonyl)methide ((CF3so2)3cr)), borate (eg tetrafluoroborate (bf4-)), phosphate ( For example, hexafluorophosphate (pf6-)), phthalates (such as hexafluoroantimonate (SbF6·)), arsenates (such as hexafluoroarsenate (AsF〇), cobalt tetracarbonyl” The fluoroacetate, and the bismuth citrate, when present, can be present in an amount of 0.05% or more, 0.10% or more, 0.15% or more, or 0.2% by weight or more. The dopant can be present in an amount of 20% or less, 15% or less, 10% or less, or 5% or less, wherein any of the upper limits can be combined with the lower limit Any one of them is combined. When a guest is present, the molar ratio of the wrong salt to the polar dopant in the matrix may be, for example, 1.5 or less, 1.3 or less, 1 or 2 or less. , 1.1 or less, 1. 〇5 or less, 〇·5 or greater, 0.7 or Large, or greater, 0.9 or greater, 0.95 or greater, where any lower limit can be combined with any upper limit. If the primary component of the matrix is less polar than PVP, nevertheless it can be polar ( For example, ionic dopant molecules further separate the moieties. The moieties that make up the metal salt of the present invention can generally interact by energy transfer (depending on the distance separating them). For example, including a blue light In the case of an ion pair emitting a cation and a red-emitting anion, the blue-emitting cation is likely to transfer all or part of its energy to the red-emitting anion (which will depend on the emission spectrum of the blue emitter) The extent of overlap between the absorption spectra of the red emitters and on the distance between the two emitters and their relative relative orientation). If the energy transfer is too much, the ion pair will be in the blue emitter The excitation of the red light is emitted -16-201041999. The ion pair emits light that can be considered white light (for example, from (0.200, 0.200), preferably from (0.260, 0.280) to (0.550 '0.500), preferably to ( Light having a CIE 1931 coordinate (x, y) in the range of 0·460, 0·500) generally requires a sufficient distance between the emitting portions. The higher distance the stomach reduces the extent of energy transfer between the emitting portions of the stomach and the like. The distance between the emitting portions having complementary emission spectra causes the energy transfer to occur to such an extent that both of the two portions emit zero and have a relative intensity such that the human eye perceives the light mixture as white light. , will receive white light emission. The case of an ion pair as described in the above examples can be extended to include more than two emission species. For the performance of the present invention, it is advantageous to select the emission portions constituting the wrong salt in such a manner that their emission spectra are complementary, that is, when each of the emission portions emits light of sufficient intensity, their emission spectra are covered. A sufficiently large portion of the visible spectrum is produced to produce white light emission. A sufficient amount of the intensities can be satisfied by adjusting the distance between the emitting portions, such as by adjusting the polarity of a surrounding substrate as described above. The appropriate distance between these parts depends on the nature of the selected part. This distance can be determined by those skilled in the art using the guidance provided in this application. For white light emission, although there is an ideal distance range between the emitted portions for each type of fault salt, too large a distance usually results in a small deviation from white light and too small a distance usually results in self-white light. More deviations (light is easily red-shifted when the distance between these parts is too small). Preferably, 'Μ, and M2 are both metal complexes. The main advantage of this embodiment is to ensure phosphorescence from the two parts of the wrong salt. Pure -17-201041999 organic molecules (in this case, the opposite of metal complexes) are usually fluorescent. If carrier recombination occurs on the organic molecule and no energy transfer occurs, this may result in a loss of efficiency. Another advantage is the simplicity of obtaining a charged emitter by using a metal complex. Finally, the charge in these complexes is usually internal, ie the charged metal ion has been surrounded by multiple ligands, especially in the case of octahedral complexes, but in organic molecules' The charge is usually at the periphery because they are derived from the grafting of charged substituents. Since electrostatic attraction is highly dependent on the distance between charges, a stronger interaction is expected when using organic molecules, which requires separation of more polar polymers or stronger electric fields for white light emission. Examples of suitable metals (4) or M2 are luminescent, charged, complexes of silver, ruthenium, money, osmium, uranium, gold, hungry, zinc, cadmium, mercury, copper or silver. A preferred metallic enthalpy!* Mz is a luminescent, charged complex of yttrium, lanthanum, cerium, lanthanum, platinum, gold, or hungry.
